[Qgis-user] Purchase of old satellite photos for small AOI

[Aron Gergely]

Hi Piotr,

Such minimum order area is the standard with the commercial imagery 
vendors. You would not get away below 20-25km2.
As an alternative you can look into:
1. Getting data from your national mapping agency - what data they have 
and whether it's free or paid,  depends entirely on your country.
     In an ideal situation they would have  annual aerial imagery 
coverage, for free..
2. Try your luck with some open archives. The coverage is spotty at 
best, but you may be in luck.
     I know of USGS Earth Explorer (https://earthexplorer.usgs.gov/) 
check out the categories
     In datasets > "commercial satellites", and "declassified data"
     You may find IKONOS-2, OrbView, or declassified spy satellite 
imagery (panchromatic only AFAIK) starting from the 60s CORONA and onwards.

Best regards,
Aron
